VERTICAL AUTOMATIC TURNING AND LIKE MACHINE TOOL.

Application filed March 20, 1925. Serial No. 17,086.

This invention relates to vertical automatic turning and like machine tools of the type comprising an intermittently rotatable bed or table provided with a plurality of rotatable neadstocks which are brought in due order, by the rotary movements of the said bed or table, into the correct positions to enable the workpieces rotated by said headstocks to be operated upon by the tools or cutters mounted on the tool slides of th machine.

The invention has for its object to provide for the ready and convenient mounting of work pieces of various forms and dimensions upon the said bed or table and in association with said rotatable headstocks, for subjection to the action of the tools, and it comprises the combination with such bed or table of means for the support of the work pieces between centres or mandrels mounted upon and partaking of the movements of the bed, and for the rotation of the work pieces between such centres.

Referring to the three accompanying sheets of explanatory drawings Figure 1 is an elevation and Figure 2 a plan of a machine having the invention applied thereto.

Figures 3 to 5 are views, to larger scales than that of Figures 1 and 2, showing details to be hereinafter referred to, Figure 3 being a sectional end view, on the line A. B. of Figure 2, and Figure 4 a sectional plan of Figure 3, showing the frame carrying the sliding headstocks and its supports, whilst Figure 5 is an elevation showing one of the said headstocks.

Figure 6 is a sectional elevation and Fig ure 7 a plan showing the centre of one of the rotatable headstocks and the carrier employed therewith.

The same reference letters in the different views indicate the same or similar parts.

As illustrated in the drawings, there is mounted above the rotatable bed a of the machine, on stems or uprights b, seating upon and secured to the said bed at positions between its multiple rotatable headstocks 0, an annular frame cl adapted to slide on the said stems b and to be secured at any position therealong relatively to theity of fixed headstocks or poppets g each fitted with a sliding centre or mandrel it having the usual conical extremity of an ordinary lathe centre, and means for sliding such centre and clamping or retaining same at any position within the range of adjustment, said means comprising a pinion 2' operated by handle and engaging rack teeth formed along said centre or mandrel h, and a clamping bolt 72 with handle nut Z. Such headstocks or poppets 9 may be made integrally with the said sliding frame d or be formed separately from the frame and mounted thereon in any convenient manner.

The said sliding centres h of the headstocks or poppets g are in alignment with coresponding centres as m carried by the multiple rotatable heads 0 of the intermittently rotating bed a. Each of such centres m has a conical extremity, as in the case of the poppet head centres h hereinbefore referred to, and also, as shown more clearly at Figures 6 and 7, a carrier 11, whereby m is coupled with the work piece as 0, represented by dotted lines at Figures 1 and 3, so that the said work piece, mounted beween a pair of aligning centres h and m, is caused to partake of the rotation of the headstock 0 in which the centre m is fixed.

The machine illustrated is provided with six pairs of centres as h and m, each pair being adapted to receive a work piece between them as aforesaid.

I claim 1. In vertical automatic turning and like machine tools having an intermittently rotating bed provided with a plurality of rotatable headstocks, the combination comprising a plurality of stems aflixed to and projecting above said bed, an annular frame mounted on said stems, and a plurality of non-rotatable sliding headstocks on said frame, each of said non-rotatable sliding headstocks being in alignment with one of the said rotatable headstocks.

2. In vertical automatic turning and like machine too-ls having an intermittently rotating bed provided with a plurality of rotatable headstocks, the combination comprising an annular frame, supporting stems for said frame affixed to and projecting above said bed, means for clamping said frame to said stems at varying positions therealong, a plurality of non-rotatable sliding headstocks on said frame, each of said non-rotatable sliding headstocks being in alignment with one of thesaid rotatable headstocks.

3. In vertical automatic turning and like machine tools having an intermittently rotating bed provided With a plurality of rotating headstocks, the combination comprising an annular frame, supporting stems for said frame aflixed to and projecting above said bed, a stay ring for the upper ends of said stems, means for clamping said frame to said stems at varying positions therealong, and a plurality of nonrotatable sliding headstocks on said frame each of said nonrotatable sliding headstocks being in alignment With one of the said rotatable headstocks.

4. In vertical automatic turning and like machine tools, having an intermittently rotating bed provided with a plurality of rotating headstocks, the combination comprising an annular frame, supporting stems for said frame afiiXed to and projecting above said bed, a stay ring for the upper ends of said stems, means for clamping said frame to said stems at varying positions therealong, a plurality of non-rotatable headstocks on said frame, a sliding mandrel in each of said non-rotatable headstocks and a non-sliding mandrel in each rotatable headstock, said mandrels being coaxial and having conical ends facing each other, and a Work carrier on the nonsliding mandrel.

In testimony whereof I have signed my name to this specification.
